Potassium Silicate

Potassium Silicates are a family of chemicals with a range of physical and chemical properties. The character of the products is determined by the ratio of silica to alkali and by the solids content. Although Potassium Silicates resemble Sodium Silicates in their basic composition, their industrial uses vary significantly. Potassium Silicates are water-soluble products of potassium oxide (K2O) and silica (SiO2) manufactured from potassium silicate glass, which is produced in furnaces by melting high purity sand with potassium carbonate. Potassium Silicates are alkaline and available in a range of SiO2: K2O ratio as liquids, flake glass and as spray-dried soluble powder for use in numerous industrial applications.
